Changes since v7:
* Drop regulator now in a different patchset from Johan
* Fix alphabetization
Changes since v6:
* Remove allowed-modes as they aren't needed
* Remove regulator-allow-set-load
* Set regulator-always-on because the wifi chip also uses the regulator
* cts pin uses bias-bus-hold
* Alphabetize uart2 pins
Changes since v5:
* Update patch subject
* Specify initial mode (via guess) for vreg_s1c
* Drop uart17 definition
* Rename bt_en to bt_default because configuring more than one pin
* Correct (maybe) bias configurations
* Correct cts gpio
* Split rts-tx into two nodes
* Drop incorrect link in the commit message
Changes since v4:
* Address Konrad's review comments.
Changes since v3:
* Add vreg_s1c
* Add regulators and not dead code
* Fix commit message changelog
Changes since v2:
* Remove dead code and add TODO comment
* Make dtbs_check happy with the pin definitions
